PlVCTMHIINGE FOR Wi ETAL WINDOWS.

SEECIFICATION forming part of Letters Patent No. 747,189, dated December 15,-.1 9103.

Application led October 2, 1902.

To a/Z whom t may concern:

Be it known that I, JOHN A. KNIsELY, a citizen of the United States, residing at Chicago, in the county ot Cook and State of Illinois, have invented certain new and useful Improvements in Pivot-Hinges for Metal Windows, of which the followingis a specification.

My invention relates to improvements in means for pivotally hiuging a sheet-metal window-sash and a sheet-metal window-frame when the frame and sash are constructed according to the designs shown in my separate applications for Letters Patent executed of even date herewith.

The objects of myimprovements are to provide a hinge-pivot the parts of which adapt themselves tothe forms of sash and frame described in said applications, in which provision is made for -the adjustment of the hinge,made necessary by the unequal settling of the masonry supports for the windowframe, in which the sash can be rotated to present the outside of the light or glass to the inside of the frame, thus facilitating the washing of same, and in which the sash and frame will be stiffened at the pivotal point.

In the accompanying drawings,which form a part of this application, Figure l is an elevation of a section of window frame and sash to which my improved hinge is attached, the sash being shown in its closed or vertical position. Fig. 2 is an elevation of the parts shown in Fig. 1, but with the sash tilted or in an open position, and in `dotted lines is shown the position the sash will assume when rotated. Fig. 3 is an elevation of the pivot or pin leaf of my improved hinge. Fig. 4 is an edge view of the part shown in Fig. 3. Fig. 5 is a top plan view of the part shown in Fig. 3. Fig. 6 is avew, partly in elevation and partly in vertical section, showing the socket or receiving member of my hinge and the method of attaching it to the windowframe.

Referring to the drawings in detail, A and B represent, respectively,sheetmetal window frame and sash having interlocking flanges or tongues of the style described in my applications for Letters Patent above referred to.

C represents the glass or window-light, which is seated in a suitable channel in the sash, and D represents generally my im- Van angle with said flange.

Serial No. 125,638. (No model.)

proved pivot-hinge, which will be described in detail.

The hinge is composed of two members d and d',the former rigidly attached to the sash and the latter adjustably attached to the Window-frame. The memberdis composed of flat cast-m etal plate adapted to fit over the projecting ange of the sash, to which itis secured by suitable screws or rivets and with its straight edge abutting against the walls of the glassreceiving portion of the sash, as shown in Fig. l. Extending at right angles from the upper portion of the body of the plate is a flange d3, which ts over and covers the adjacent edge of the projecting sash-dange, and from this flange extends a wing d, in the outer end of which the pivot-pin d2 is xed. The wing is cast considerably thicker than the body of the plate CZ in order to give it the requisite strength, its diameter' being about two-thirds of the height of the flange d3, thus forming Where the wing joins the iange at the lower end, a notch d5 is formed by cutting away a portion of the wing and beveling the end of the ange, as shown in Fig. 3, this inset or notch being adapted to receive a correspondingly-projecting portion of the member d', to be described. When the member d is attached to the sash, its lower half is adapted to tit under the overhanging iiange b' of the frame A when the sash is in its closed position, the thickness of the plate d being such that While itwill slide or move under said liange it will at the same time serve to press the sash toward the frame and effect a comparatively tight closure therebetween. It will be seen that the pivot-pin projects toward the frame, its outer end terminating near the face of the latter. The pivot-pin enters a suitable hole provided therefor in the member d and indicated in dotted lines. This hole extends through the upper portion of the member d', which is thickened, as at d6, to provide ample bearing for the pin. Slots (Z7 extend through the plate d', by which the plate may be vertically adjusted on the screws d8, which pass through the slots and engage threaded holes in the plate dg, which is secured at the rear side of the frame A, as shown in Fig. 6. The mem-l ber being adjusted, the screws are tightened, and the plate is thereby held in place.

It will be noted that when the sash is turned on its pivot-hinge the full limit the projecting flange of the sash will strike against the flange b' of the frame, and thus limit the rotation of the sash.

In applying my improved hinge I first secure the member d in its normal position, then place the sash in its frame, and then secure the member to the sash to which the pin is fixed, the end of the pin being irst placed in the hole or socket provided in the member d. When the two members are parallel or in the position assumed when the sash is closed, the chamfered upper end of the iiange :c of the member d lits into the notch d5 of the member d, thus permitting a close joint between the parts at that point.

In windows of the class to which my improved pivot-hinge applies particularly it is important to have the sash turn freely from its open to its closed position, as such closing is usually automatic when it is desired to shut out re from the building equipped with such windows. With my form of hinge it will be seen that the frictional contact at the hinge when the Window is open is only between the raised portion d6 of the member d and the portion of the wing d4, which immediately surrounds the pin d2, thus permitting the sash to respond at once when released. Not until the sash is nearly closed does the lower portion of the member d enter under the projecting and overhangiug Iiange b, at which time the sash has gained such momentum that the member will be forced to enter the groove under the flange, and thereupon it will push the outer face of the sash-stile against the adjacent face of the frame, and thus effect a non-rattling closure.

The extent of this wedging or contact can be regulated by bending the ange b in or out, thus increasing or diminishing the size of the groove into which the lower part of the memberd moves when the sash is brought to its closed position.

Having thus described the form, construction, and operation of my invention, what I claim as new, and desire to obtain by Letters Patent, is-

1. A hinge composed of a fixed member, and an adjustable member, the xed member formed with a lateral wing having a pivot-pin extending at right angles therefrom and the adjustable member having a raised portion perforated to receive the said pivot-pin.

2. A hinge composed of a fixed member and an adjustable member, the fixed member formed with a lateral wing and with a ange as d3, a pivot-pin in the outer end of said wing, and the adjustable member having a raised portion as d, perforated to receive the said pivot-pin.
